CUTTER FOR TONGUED BOARDS.

Patented Och-23, 1906.

To all whom, it may concern:

Beit known that we, JOHN J. SonILLING and GEORGE W. SGHILLING,citizens-of the United States, residing in the city and county ofPhiladelphia, State of Pennsylvania, have invented a new and usefulCutter for Tongued Boards and the Like, of which the following is aspecification.

Our invention consists of a cutter for tongues of flooring-boards,partitions, and the like, the same embodying a blade which is adapted tobe driven into the tongues and means for withdrawing the blade after thetongues are severed or cut.

It also consistsof means for advancing the blade to a fresh place ofentrance into the tongues. I

It also consists of details of construction as will be hereinafterdescribed.

Figure 1 represents a side elevation of a cutter embodying ourinvention. Figs. 2- and 3 represent elevations of a portion of theopposite side to Fig. 1, the parts being in different positions. Fig. 4represents an end elevation of a portion. Fig. 5 represents a transversesection on line as 00, Fig. 1

Similar letters-of reference indicate corresponding parts in thefigures.

Referrin to the drawings, A designates a blade whic is connected in thisinstance by screws and nuts with the stockB, the latter being providedwith the handle C for evident purposes. The advance end of the blade ispointed, as at D, so that it may be readily driven between the joints ofboards and cut the tongues thereof, as clearly illustrated in. thedrawings. On the lower end of the stock is the foot E, which is adaptedto contact with the upper face of the boards, so as to limit the depthof penetration of the blade, and has'on the ends thereof the heels F F,which are adapted to rock on the boards in order to cause the withdrawalof the blade, as will be hereinafter further explained.

Itwill be seen that the blade is inserted between the boards and driveninto the tongue G, as shown in Fig. 2, thus severing and cutting thelatter, as shown in Fig. 4. Then the stock may be driven ahead, thuscontinuing the cutting, or it may be turned,

on the top of the boards, thus causing the withdrawal of the oint of theblade, when I "the blade again driven into position, thus further outthe tongue. completed, the point of the blade emerges from the tongue,and so the tool may be removed.

In order to automatically operate the tool to cause the same to walk, adog H is pivoted, as at J, to the stock B, its lower end K being pointedor serrated so as to take hold of the top of the boards on which itrests. It will be seen that if the tool is turned in the direction ofthe arrow, Fig. 2, the stock will turn on the heel F, and so draw thedog H after it, causing its point K to advance and take a fresh hold ofthe boards. Then when the tool is turned in the op osite direction itwill turn on the dog as a fu crum, andso advance the'tool so that theblade will cut through the tongue to a greater extent and place the toolin an advanced position so as to enter between the boards at a newplace, when the again cutting or severing-the tongue, when I the stockis operated as before, so as' to- When the work is v blade is againdriven into the tongue, cutting the same as before, and so theoperations continue, it being evident that as the dog H follows therocking motions of thestock it. imparts automatic walking and advancingmotions to the blade.

' In order to cause a penetration and proper engagement of the dogH-with the boards, the

back of said dog is formed with'a rest L, on

which the foot of the operator may be laced in order to drive said pointinto the oard, the effect of which is evident.

The end of the blade opposite to the point D has a similar point D, sothat when the former point is Worn the blade may be re- 1 moved andreversed, thus presenting the point D for operation.

Having thus described our invention, what we-claim as new, and desire tosecure byLetters Patent, is r 1. In a cutter of the character stated, ablade-carrying stock having a heel on which it may rock and havingconnected therewith means for imparting walking or advancing motionthereto.

2. A cutter of the character stated consisting of a blade, a stock carr'ng the same,

and a foot on the lower end 0 said stock to rest on top of the board,said foot having a heel on an end thereof.

.3. A cutter of the character stated,-con-,

sisting of a blade, a stock carrying the same, and a foot on the lowerend of said stock to rest on top of the board, said foot having heels atopposite ends thereof. 7

4. In a cutter of the character stated, a blade-carrying stock, havingmeans to bear on a board whereby the stock may be rocked and a dogpivotally connected with said stock and depending therefrom.

5. In a cutter of the character stated, a blade-carrying stock, havingmeans to bear on a board whereby the stock may be rocked and'a dogpivotally connected with said stock and depending therefrom, theengaging edge of said dog being serrated.
